I do yawn frequently, I was on Dr. Google trying to find out what may caused that condition. There was a time when I did an ultrasound of my throat and there was some kind of alteration in the exam. I started to think I had hypothyroidism and believe it or not Dr. Google told me 'frequent yawning' could mean something was wrong with my thyroid function. That was what I needed to confirm my diagnose.

To sum up, we will always try to diagnose ourselves with Dr. Google but somehow we have to learn how to filter all these information.
